I picked Rafael first and it was easy to get his good ending, as you just need to be nice to him, but I wasn't very happy with it. It didn't look so "good".
Then I picked Alben and I have to say Janet x Alben are my second favourites, they're good ending is really nice.
When going after Linds Janet seem to realize he and Rafael care a lot about each other and by telling Linds it's like she's trying to play matchmaker, I like to pretend she gave up on Linds realizing this and it's not actually a threesome. But of course the game doesn't say anything specific XD
